title: The delimitation of the workspace accuracy in coordinate measuring technique.
abstract: Dimensional measurements based on coordinate metrology are widely used for product verification, process control and dimensional faults root causes diagnostics of various manufacturing processes. In this study, the results of the measuring surface scanning of coordinate measuring machine with the prototype of optoelectronic device have been presented. The presented device is able to determine actual (real) inaccuracy of the CMM in two axes (X, Y). The prototype scanning device is installed in the measuring probe place. The method makes possible scanning with the established accuracy (max. 0.1 µm). A short description of the new method and the device is added, and some initial results are discussed. The results concern the inaccuracy of the CMMs example measuring area.
